The three measures of meal, which together make an ephah, were the understood quantity of an ordinary batch in the economics of a family, and as such are several times incidentally mentioned in the Scriptures of the Old Testament. See, for example, the preparation of bread by Sarah, as it is narrated in Gen. xviii. The various suggestions which inquirers have made regarding the specific significance of the three measures of meal, are interesting and instructive. As they do not directly traverse the lines of the analogy, they are entitled to a respectful hearing; but the subject is subordinate, and the meaning must ever be comparatively obscure. Whether the three measures are understood to point to the three continents of the world then known, or to the three sons of Noah by whom the world was peopled, or to spirit, soul, and body, the constituent elements of human nature, an interesting and useful conception is obtained. Each of these suggestions contains a truth, and that, too, a truth which is germane to the main lesson of the parable.

The same historic incidents which show that three measures were the ordinary quantity, show also that the women of the house were the ordinary operators. Baking the bread of the household was accounted women’s work; as men ploughed and sowed in the field, women kneaded and baked at the oven. An inversion of this order would have been noticed as incongruous, and presented a difficulty. Exceptions may be found, both in ancient and modern times, but the representation in the text proceeds obviously upon the ordinary habits of society. On this account, although I willingly listen to interesting and ingenious speculations regarding the significance of the woman who hid the leaven among the meal, I cannot accept them as the foundation of any positive doctrine. I am jealous, not without cause, of ecclesiastical tendencies and prepossessions in the interpretation of the parables. It is quite true that both in the discourses of the Lord and in the epistles of his followers, reference is made sometimes to the community or communities of believers constituted as a Church; but the Church in the Scriptures is a much simpler affair than it is in ecclesiastical history. Moreover, in these lessons which were taught by the Lord in the beginning of the Gospel, we find much about the individual man, and about the aggregate of mankind, but little about the Church in its visible organization. Accordingly, while I endeavour to keep my mind open for everything that the Scriptures bring to the Church, I am disposed to shut the door hard against anything that I suspect the Church is bringing to the Scriptures. When the woman who kneaded the dough, and the woman who lost and found the silver coin, come forward, backed by much learned authority, saying, We are the Church, I stand on my guard against deception, and carefully examine their credentials. A man took the mustard-seed and sowed it in his field; a woman took the leaven and hid it in three measures of meal. The two parables are in this respect strictly parallel; in both alike an ordinary act in rural economy is performed, and in either it is performed by a person of the appropriate sex. The converse would have been startling and inexplicable. Whatever the operator may represent in the sowing of the seed, the operator in the hiding of the leaven represents the same. To neglect the strict parallelism between the two cases, and attribute some meaning to the selection of a woman as the operator in the one, which the selection of a man in the other does not convey, is, as I apprehend the matter, to forsake the main track of the analogy, and follow by-paths which lead to no useful result. The same divine hand that dropped the word of eternal life as a mustard-seed into the ground, also hid the word of eternal life as leaven in the ephah of flour. Looking to the spiritual significance of the two parables, we have in both cases the same act, and in both cases, therefore, the same actor.[19]

A question of deep interest and considerable difficulty arises from the fact that here, and here only, the greatest good—the kingdom of God in the world—is unequivocally compared to leaven, whereas this similitude, in all other places of Scripture where it occurs, either stands indefinitely for progress of any kind, or expressly represents the energy of evil. I assume without argument that in this parable the diffusion of leaven through the mass represents the diffusion of good in the world, although here and there, both in ancient and modern times, an inquirer appears who understands the leaven in this place to predict the prevalence of false doctrines and practices in the Church. This interpretation no man would voluntarily adopt in the first instance, for it is obviously incongruous with the signification of the kingdom in every other parable of the group; but some have permitted themselves to be driven into it by a difficulty that threatens on the opposite side. Because in other portions of Scripture they find leaven employed as an emblem of evil, they think themselves obliged to take it as a representative of evil here. But the difficulty which is presented by the use of a type to denote good, which is elsewhere employed to denote evil, must be fairly met and explained: to escape an imaginary difficulty we must not plunge into a real mistake. I am convinced that here, as in many similar cases, that which at first sight and on the surface wears the appearance of harshness, will be found, on fuller consideration, to contain a new beauty, and impart additional power.

It is obvious, in the first place, from the references made to it both by the Lord and his apostles, and especially from the iteration of the same maxim by Paul in two distinct epistles, that the similitude was current and familiar among the people as a proverb. It is conceded, that apart from this parable, wherever its application is expressly indicated, it is employed to designate the progress of evil; but it ought to be borne in mind that Paul has twice, in the same words, enunciated the universal proposition, “A little leaven leaveneth the whole lump” (1 Cor. v. 6; Gal. v. 9). By expressly mentioning the leaven of malice and wickedness in connection with this proposition, he leaves room for the supposition that there may be also a leaven of truth and holiness. In like manner, the Lord in another place warns his followers to beware of the leaven of the Pharisees, which is hypocrisy; but he nowhere says that leaven is hypocrisy. Leaven does, indeed, illustrate the method in which falsehood spreads; but it may, for aught that is said in the Scriptures, illustrate also the manner in which truth advances, when it has gotten a footing in the world or in a man. If truth and error, though opposite in their nature, are like each other in their tendency to advance, as if by contagion; and if error is in this respect like leaven, then truth must be in this respect like leaven too. When two things are in a certain aspect like each other, and one of them is in the same aspect like a third thing, the other must also be like that third thing, provided the point of view remain unchanged. Leaven represents evil not in its nature, but only in the manner of its progress; and in this respect the symbol is equally applicable to the opposite good.

This argument, indeed, may be carried one step further. It is not enough to show that no loss of meaning is sustained by the application of this analogy to a new and opposite class of facts; a positive gain thereby accrues. The circumstance that in all other places of Scripture in which the symbolical meaning of leaven is specifically applied, it is, in point of fact, employed to designate the progress of evil, instead of obscuring, rather reflects additional light on the comparison as it is used in this parable. The Teacher who speaks here is sovereign. By him the worlds were made, and by him redemption wrought. In both departments he executes his own will: when he speaks, he speaks with authority. Observing that the principle which ordinarily enters and pervades human hearts is evil, a leaven of hypocrisy, he does not submit to that state of things as necessary and permanent: this is, indeed, the condition of the world; but he has come to change it. Such is the direction of the current, and the proverb which compares moral evil to a leaven correctly describes its insinuating and persevering course; but here is one who has power to turn the river of water so that it shall flow backward to its source. Corruption has, indeed, spread through the world as leaven spreads through the dough, but here is Truth incarnate, another leaven, introduced into the mass, having power to saturate all with good, and thereby ultimately to cast forth evil from the world. The kingdom of darkness, for example, comes secretly,—the wiles of the devil constitute his policy and secure his success; the kingdom of God, although opposite in essence, is similar in the method of its advance, for it “cometh not with observation.” The wheat and the darnel were opposite in character and consequences as light and darkness, but they were precisely alike in the manner of their growth. The loyal army adopts the same tactics which the rebels employ, while it strives to defend the throne which they are leagued to overthrow.

Thus, it is not enough to say that although the diffusion of evil in God’s intelligent creatures is like the diffusion of leaven in the dough, Jesus may notwithstanding employ the same analogy to indicate how grace grows: we may proceed further and affirm, as Stier has ingeniously suggested, that because evil has often been compared to leaven in the manner of its advance, Jesus adopts that similitude to illustrate the aggressive, pervasive power of the truth.

Boldly, as a sovereign may, this Teacher seizes a proverb which was current as an exponent of the adversaries’ successful stratagems, and stamps the metal with the image and superscription of the rightful King. The evil spreads like leaven; you tremble before its stealthy advance and relentless grasp: but be of good cheer, disciples of Jesus, greater is He that is for you than all that are against you; the word of life which has been hidden in the world, hidden in believing hearts, is a leaven too. The unction of the Holy One is more subtle and penetrating and subduing than sin and Satan. Where sin abounded grace shall much more abound.

The appropriation by Christ and to his kingdom of a similitude which had previously been applied in an opposite sense may be illustrated by many parallel examples in the Scriptures.[20] Of these, as far as I know, the different and opposite figurative significations of the serpent are the most striking and appropriate. The conception of secret motion, followed in due time by a surely planted effectual stroke, which is associated with the faculties and habits of a serpent, Christ found appropriated as a type to express the power of evil: but he did not permit it to remain so appropriated; he spoiled the Egyptian of this jewel, and in as far as it possessed value, enriched with it his own Israel. The serpent, as a metaphor, was in practice as completely thirled to the indication of evil as leaven had been, but Jesus counselled his disciples to “be wise as serpents.” A similar example occurs in the parable of the unjust steward: it teaches that the skill of the wicked in doing evil should be imitated by Christians in doing good. Christ acts as king and conqueror. He strips the slain enemy of his sharpest weapons, and therewith girds his own faithful followers. Whatever wisdom and power may have been employed against them, wisdom and power inconceivably greater are wielded on their side.

We shall be better prepared to appreciate for practical purposes the peculiar meaning which the symbol bears in this parable if we advert, in the first place, to its ordinary meaning in other parts of Scripture. Both in the typical worship of the Old Testament and in the doctrinal teaching of the New, leaven is ordinarily employed to denote the insinuating, contagious advance of sin. When the Hebrews were instructed to cast all leaven out of their houses during the solemnities of the Passover, their lawgiver meant to teach them by type that in worshipping God through his ordinances they should cast all malice and wickedness out of their hearts. In like manner, when the great Teacher warned his followers to beware of the leaven of the Pharisees and of the Sadducees, he meant that they should eschew on the one hand the lie of self-righteous superstition, and on the other the lie of libertine unbelief. The Apostle Paul, too, while he does not forbid another use, employs the conception, in point of fact, to illustrate the presence and power of sin.

Evil is a mysterious, self-propagating principle, like leaven. In the fact of the fall a piece of this leaven was hidden in the mass, and all mankind have consequently become corrupted. The leaven of sin that touched humanity at the first has infected the whole. The fact of a universal corruption appears in all history, and its origin is explained in the beginning of Genesis. The whole lump has been leavened: break off a bit at any place, at any time, and you will find it tainted. “The innocence of childhood” is a fond, false phrase, employed to conceal the terrible reality: there is no innocence, no purity, except that which comes through the gift of God, the sacrifice of Christ, and the ministry of the Spirit.
